CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 13/420,603, filed Mar. 14, 2012, now U.S. Pat. No. 8,821,257, issued Sep. 2, 2014, which claims priority to and the the benefit of U.S. Provisional Patent Application No. 61/452,554, filed on Mar. 14, 2011, the entire contents of each of which are incorporated herein by reference.

BACKGROUND

In the field of economic markets, participants in a market are able to trade shares in a variety of different goods. For example, participants in the NYSE and NASDAQ stock markets use computer systems to buy and sell shares of public corporations.

As another example, participants in prediction markets (such as the Intrade™ prediction markets) can trade “shares” in whether various events such as whether a particular film will win the Academy Award® for Best Picture or whether a particular political candidate will win an upcoming election. Owners of these shares are paid if their predictions are turn out to be correct. For example, in a race between Candidate A and Candidate B in which each share would pay out $10 to the shareholder once the election was decided, the share prices for Candidates A and B would vary over the course of their election campaigns based on the market participants' perceptions of the probability that either candidate would win the election. Participants would buy and sell shares based on mismatches between their value and the current market values until such issues were resolved.

In a way similar to that of electronic stock markets, prediction markets are typically also built and run on computer systems which manage the orders placed by the participants and operate to execute the trades.

SUMMARY

Embodiments of the present invention are directed to a system and method for operating a market in competitive sports based on ranking.

According to one embodiment of the present invention, a computer system for providing a market for a plurality of participants to invest in a plurality of shares of corresponding competitors includes: a central processing unit; memory coupled to the central processing unit; a data bus coupled to the central processing unit; a persistent storage device coupled to the data bus; and a network interface device coupled to the data bus, the computer system being configured to: store a plurality of share holdings of the participants; store a plurality of credit balances of the participants; and redeem shares at the conclusion of a period, wherein the computer system is configured to redeem shares by calculating an amount that the credit balance of each participant should be modified in accordance with a plurality of values of corresponding ones of the shares at the conclusion of the period and the share holdings of a corresponding participant of the participants, and wherein the values of the shares at the conclusion of the period is determined based on a benchmark ranking of the competitors at the conclusion of the period.

The values of the shares corresponding to a highest ranked competitor of the benchmark ranking may be greater than the values of the shares corresponding to a lowest ranked competitor of the benchmark ranking.

The value of the shares associated with a competitor of the competitors may decrease linearly with the decreasing rank of the competitor in the benchmark ranking.

The competitors may be sports teams.

The benchmark ranking may be a poll.

DETAILED DESCRIPTION

In the following detailed description, only certain exemplary embodiments of the present invention are shown and described, by way of illustration. As those skilled in the art would recognize, the invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Like reference numerals designate like elements throughout the specification.

Aspects of embodiments of the present invention are directed toward a system for an online and mobile phone application for pari-mutuel trading and investing in “SportShares” of teams, the final (or redemption) value of the shares being based on the poll rankings of sports (or athletic) teams at the end of the season. Embodiments of the present invention use polls or rankings to determine value, rather than individual contests and therefore focus on investing, not wagering.

For example, embodiments of the present invention may use the official pre-season, weekly, and the annual season-ending, Associated Press® (AP) Top 25 poll, to determine the net present and future expiration value of each sports team in the competition.

Embodiments of the present invention are directed to the use of any poll or ranking to value any team in any sport. For example, rankings from the Associated Press®, ESPN®, Sports Illustrated®, and other news organizations or official rankings such as the NASCAR® Sprint Cup Series® Standings, Association of Tennis Professionals® (ATP), Women's Tennis Association® (WTA), Professional Golfers' Association® (PGA), and other professional sports associations' rankings may be used as the ranking for determining the value of a team or player in a sport within a pari-mutuel trading and investing system according to embodiments of the present invention. For non-revenue college sports, an appropriate sport-specific poll, e.g., Baseball America or Hockey News, may be used to determine the values of the teams for that sport.

For example, in a season-end poll in which 25 teams are ranked, SportShares of the team that finishes the sports season ranked #1 in their sport's respective AP (or other benchmark ranking) Top 25 poll will expire worth $25 (or other dollar value related to the number of teams that appear in the benchmark poll). The second place finisher will expire worth $24, the third place $23, etc. The 25th ranked team in each season's final poll will expire worth $1. If a given sport ranks only 20 teams, then the champion will expire worth $20.

More generally, in a benchmark poll that ranks N teams, each SportShare of the #1 ranked team will be worth (or redeemed at) $N, each share of the #2 ranked team will be worth $N-1, and so on, with shares of the Nth ranked team being worth $1. In other embodiments of the present invention, the relationship between the rankings and redemption value of the shares may be different. For example, in some embodiments, the payouts may be made with different scaling factors, such as shares of the #1 ranked team being worth $N/100 or the payouts may monotonically (e.g., linearly, polynomially, or exponentially) decrease as a function of rank.

In some embodiments, the values refer to credits or “play money” which do not directly correspond to any monetary value, while in other embodiments, the values correspond to actual funds that exchange hands between participants and the system. In some embodiments of the present invention, players are initially issued a set number of credits and can purchase additional credits from the system for a fee.

According to one embodiment, SportShares of teams that fail to earn a Top 25 ranking in the season ending benchmark poll expire worthless (e.g., a redemption value of $0). In other embodiments, the number of teams ranked is greater than or less than 25.

For example, the University of Alabama Crimson Tide football team finished the 2009-10 season ranked #1 in the Associated Press Top 25 poll. Therefore, Alabama's SportShares expired at $25 per share. The number 10 ranked team in the poll expired at $16 per share. SportShares in Oklahoma State, which did not make the Top 25 poll, expired at $0 per share.

Between the pre-season poll and the final season-ending poll in any given sport, the values of the teams' SportShares will fluctuate based on the market's (e.g., the market participants') predictions and valuations of each team's prospects for achieving a given final ranking (e.g., the team's expected final ranking).

In addition, in some embodiments of the present invention, the values of the teams' SportShares may fluctuate based on the results of other polls released between the pre-season poll and the final season-ending poll. In one embodiment of the present invention, the participants do not trade SportShares with one another and instead trade with the system, and the value of a team's SportShares depends only on the team's current ranking as determined, for example, by a weekly mid-season poll.

FIG. 1 is an functional diagram illustrating a system according to one embodiment of the present invention. As shown in FIG. 1, participating investors 16 access an application or website (which may be referred to as the “SportShares application”) running on server 10 over a network 14 via an application or a web browser, either of which may run on an end user device 12, which may be a mobile device (such as a mobile phone, a tablet, or a laptop), a computer, or other communications devices as are well known in the art. The network 14 may include the internet, a local area network, cellular telephone networks, satellite networks, and combinations thereof, as are well known in the art for communicating digital information.

FIG. 2 is a block diagram illustrating components of a computer system which may be used to run the SportShares application. Referring to FIG. 2, according to one embodiment of the present invention, a server 10 includes a central processing unit (CPU) 102, memory 104 for storing data and program instructions (e.g., program instructions related to the SportShares application), a data bus 106 for the CPU to communicate with peripheral devices, a persistent storage device 108 (such as a hard disk drive, a solid state drive, other flash memory) for storing participant data (e.g., in a database structure), and a network interface device 110 for communicating with other computers. Other embodiments of the present invention may use computer systems having different architectures or different arrangements of components.

In other embodiments of the present invention, the SportShares application may run on a plurality of servers configured to perform similar functions or different functions. For example, a plurality of servers may each run substantially the same software and each server may manage both the user interface and data storage (e.g., in a database) for the SportShares application, with participants directed to particular servers by a load balancing server. As another example, a first server (or a plurality of servers) may be dedicated to providing participant interaction and a second server (or a plurality of servers) may be dedicated to data storage.

FIG. 3 is a functional block diagram illustrating components of the SportShares application. In one embodiment, these components may be implemented in software running on the server 10. The software may be built on a variety of operating systems and software platforms that are well known in the art such as a Linux, Apache HTTP server, MySQL database, and PHP (LAMP) stack or similar systems built on other operating systems (e.g., Windows, BSD, OS X, etc.) with different web server software (e.g., Microsoft™ Internet Information Services), different database software (e.g., PostgreSQL, Microsoft™ SQL Server, Oracle™ RDBMS, etc.) and different scripting languages (e.g., JavaServer Pages, Perl, Python, etc.).

In one embodiment of the present invention, a participant signs up for an account to obtain a username and a password (e.g., via an account management interface and storing the username and a hash of the password in the users database 318), and, once issued a username and password, participants can log in to the system and open and fund their SportShares investment and trading accounts (e.g., via a deposit/withdrawal interface 308). FIGS. 4, 5, and 6 are screenshots illustrating a user interface for adding credits to the participant account using a bank account, credit card, and other funds, respectively. In some embodiments, the SportShares investment and trading accounts are initially funded with a limited supply of “free” credits. In some embodiments of the present invention, commissions may be charged for the execution of trades. In some embodiments of the present invention, a basic membership is free and accelerated subscription packages which may provide access to additional information (e.g., real-time quotes, more extensive charts and analysis, increased integration with news feeds) may be available for an additional fee.

Once the account is opened and funded, participants can buy, sell, and trade SportShares via the application or website in a pari-mutuel manner with other participants, which may include friends, investment groups, and strangers. As described above, in other embodiments of the present invention, participants buy and sell SportShares directly from the SportShares application (e.g., shares issued or bought back by the SportShares application, without interaction with other participants) at prices determined by the most recent poll rankings. Orders may be placed via the order input interface 302. FIG. 7 is a screenshot of an order input user interface according to one embodiment of the present invention.

Customers can also post and leave open buy/sell trading orders on different teams' SportShares to be transacted later, with another participant, if or when the proposer's/acceptor's bid/ask price is met, whereupon a trade notice is transmitted to each participant in that particular transaction, and their trading accounts are debited and credited accordingly.

Participants can “go long” (i.e., buy SportShares) or “sell short” (i.e., sell SportShares that they do not own). The current share price will be determined by the equilibrium between the Bid price, i.e., those traders looking to buy a given SportShare at the market's highest price offer, and the Ask price, or the lowest price at which traders are looking to sell SportShares in a given team are willing to sell their shares. FIG. 8 is a screenshot of a portion of the user interface which provides an overview of current SportShares prices according to one embodiment of the present invention.

After a participant has entered an order into the SportShares application, a rules verifier 310 (see, e.g., FIG. 3) checks to determine if the order complies with particular rules. For example, when buying SportShares, the rules verifier 310 may determine if the participant has enough cash in his account to purchase the desired shares at the requested price or, when selling SportShares, the rules verifier 310 may ensure that the participant has enough shares in his portfolio (or enough cash in his account when short selling) to cover the sale.

If the order is rejected by the rules verifier 310, the participant is presented with a request to correct the order to make it compliant with the rules enforced by the rules verifier 310 or to cancel the order. Once an order is accepted, the order is entered into the orders database 312 while it waits for processing by the order processor 322. FIG. 9 is a screenshot listing a participant's pending orders, according to one embodiment of the present invention, which may be viewed via a status user interface 304.

When a participant buys SportShares of a given team, the participant's trading account is deducted the amount of the purchase price multiplied by the number of shares traded in a manner similar to that of trading stock in public corporations. FIG. 10 a is a screenshot illustrating a participant's portfolio of shares according to one embodiment of the present invention in which shares are traded for points. FIG. 10 b is a screenshot illustrating a participant's portfolio of shares according to another embodiment of the present invention in which shares are traded (e.g., bought “long” or sold “short” for deposited cash).

FIG. 10 c is a screenshot illustrating a scoreboard showing a game in progress with current prices according to one embodiment of the present invention. Over the course of the game, live, current game scores and time remaining in the game (if applicable) may be shown alongside prices of shares in the competitors involved in the game. The market prices (e.g., bid/ask prices) of the teams may fluctuate in real-time based on the performance of the teams as participants change their valuations of those teams and modify their orders to increase or decrease their bid or ask prices. In addition, a running stream (similar to a stock ticker) of recently completed trades (e.g., UCLA 10 shares @ $14.50) may also be provided in real-time. Such a ticker may be displayed in, for example, a browser or in a mobile application. For example, FIG. 10 c also illustrates a running ticker below the scoreboard. However, the ticker may also be displayed in other portions of the application, such as on a trading (or order placement) page, on an initial landing page, and on a pending orders page.

When a participant sells SportShares, the participant's account is credited with the sale price multiplied by the number of shares, but the seller's account is deducted for credit authorization purposes, the dollar difference between the agreed upon trade price and $25 (i.e., the figure of maximum risk) or whatever the corresponding value minus the sale price of the benchmark poll for that sport. This keeps any participant from selling more shares that they are able or willing to honor, as each seller is (temporarily) deducted the full exposure risk amount of the trade, worst-case assuming the sold SportShares expire with the corresponding team in first place (e.g., worth $25 per share).

In one embodiment, the SportShares are traded in a “pari-mutuel” marketplace, in which a participant can only Buy or Sell as many shares as the participant is able to convince other participants to Sell or Buy. Therefore, orders may only be partially filled based on supply and demand and prices may have to be adjusted to complete an order. In other words, participants may “issue” shares by selling short and those shares may be traded among the other participants.

In another embodiment, the SportShares are traded solely with the SportShares application (e.g., with the SportShares service), which may buy and sell shares based on rankings as determined by the current polls (e.g., a weekly mid-season poll or ranking), the prices being based on the mid-season ranking in substantially the same way that prices are determined at the end of the season based on the post-season ranking.

In one embodiment, at the end of the season, the benchmark Top 25 poll (or post-season ranking) determines the official expiration price of each team's respective SportShares. $25 for #1, $1 for #25, and all positions in between. Participants' accounts are credited and debited accordingly by the redemption processor 324 based on the contents of the participants portfolios (which are stored in the portfolio database 316). In some embodiments, the subsequent SportShares season begins the day following the end of the previous season (e.g., the day the benchmark poll is released). FIG. 11 a is a screenshot of a ranking of teams along with links for a participant to purchase or sell SportShares in those teams according to one embodiment of the present invention in which SportShares are traded for points. FIG. 11 b is a screenshot of a ranking of teams along with links for a participant to purchase or sell SportShares in those teams according to one embodiment of the present invention in which SportShares are traded for cash. FIG. 12 is a screenshot showing unranked teams with links to allow a participant to purchase SportShares in those unranked teams according to one embodiment of the present invention.

FIG. 13 is a flowchart illustrating a method of crediting and debiting participants' accounts at the end of a season in accordance with one embodiment of the present invention. For each participant i (or participant) having a corresponding portfolio of shares (or portfolio) (402), the redemption processor 324 iterates through each of the types of shares (or share_(j)) in portfolio_(i) (404), determines the final value of one share of share_(d) based on the final benchmark poll (as described above) (406), adds the value of the product of the number of shares of share_(j) in portfolio_(i) (408) until it has iterated through all of the shares in portfolio_(;) (410), and repeats the process for each participant_(i) having portfolio_(i) (412).

FIG. 14 is a flowchart illustrating a method of updating the value of a share based on a change in power rankings according to one embodiment of the present invention.

In some embodiments, the shares are redeemed by the SportShares application. In other embodiments, the shares are redeemed from the cash accounts of the participants.

In one embodiment, the SportShares application also allows a participant to make cash withdrawals from his account. FIG. 15 is a screenshot according to one embodiment of the present invention illustrating a component of the user interface of the SportShares Application which allows a participant to withdraw cash funds from his account (e.g., to be deposited into his bank account or sent as a check).

In some embodiments of the present invention, the SportShares Application further includes a social networking layer. FIG. 16 is a screenshot according to one embodiment of the present invention illustrating a participant's profile, which may include information such as the participant's favorite teams, the participant's current stats (e.g., points earned, win/loss record, portfolio value), a list of the trophies (or badges) earned by the participant by completing particular tasks, etc.

Participants may also choose to associate with other participants via a “friend” mechanism similar to the systems used on social networking sites such as Facebook and LinkedIn. FIG. 17 is a screenshot of a user interface according to one embodiment of the present invention for searching for other participants to add or connect to as “friends”. FIG. 18 is a screenshot of a user interface according to one embodiment of the present invention of a user interface listing “friends and rivals” that a participant is associated with.

In one embodiment of the present invention, other actions taken by other participants (e.g., “friends”) may be shown to a participant in an activity feed. FIG. 19 is a screenshot of an activity feed according to one embodiment of the present invention in which, for example, the recent purchases and sales of SportShares by friends and recent addition of new friends can be publicized in the activity feed. In some embodiments of the present invention, participants can leave comments regarding these events (e.g., the trades) in the activity feed.

FIG. 20 is a screenshot of leaderboards which show current ranks of participants based on point totals may be displayed according to one embodiment of the present invention. These leaderboards may show the current standings across the entire platform (e.g., “SportsGunner Nation”) and may also show standings among a circle of friends. In another embodiment of the present invention, as shown in FIG. 21, specific leaderboards can be shown based on sport, region or cities, time period (e.g., week, month, season), and ranking criteria (e.g., number of points earned, percentage increase in points, total points, portfolio size, total wins, and number of trades).

In another embodiment of the present invention, participants can make predictions as to whether a given team will go up, go down, or remain in the same position in the rankings during a given week. Participants may score points in accordance with the number of accurate predictions made. FIG. 22 is a screenshot illustrating an interface for inputting predictions according to one embodiment of the present invention.

FIG. 23 is a screenshot illustrating an interface for managing membership in and status of competitive “leagues” according to one embodiment of the present invention in which multiple participants trade SportShares and compete to end up with the best portfolio by the end of a season.

FIG. 24 is a screenshot illustrating an interface for viewing most recent open orders according to one embodiment of the present invention. According to one embodiment, the list of recent open orders also includes an option for the current participant to complete the order by selling or buying shares at the price offered in the open order.

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claim, and equivalents thereof.

For example, embodiments of the present invention may be directed to rankings of competitors other than those of sports teams and individual athletes, such as college rankings, chess rankings, sales representatives by revenue, etc.
